Title: Fishing hook
Inventor: SITTON GARY L
IPC: A01K83/00
Filed: 1985-05-16
Abstract: A monolithic molded plastic fishing hook connectable to a monofilament fishing line has an elongate body of uniform cross-section. A looping reverse curve part (14) connects the body with a barbed point which penetrates a fish in the direction of line connection part (13). The barbed point may be provided with spurs (125, Figure 8) on which bait may be impaled. The shape of the hook is such that it provides a shock absorber action during catching a fish, enables release from a hooked snag before the line breaks, and maintains the axis of penetration of the barbed point parallel to the line of action while under tension. <IMAGE>

Title: Liquid crystal displays as detectors of static charges & electric fields
Inventor: DUNNING GEORGE ERNEST
IPC: G01R13/40
Filed: 1986-07-01
Abstract: The liquid crystal display of the type commonly used in digital watches, has been adapted to form a visual sensor of externally collected electric charges. It has been discovered that by applying a charge from a collecting plate to two separated segments within the lower face of the display, the whole register becomes activated. This also increases the sensitivity of the display as a detector and enables static charges and electric fields to be virtually seen when the device is held by an insulated handle 6 with contact made to ones person via a button 7 connected to one of the display terminals. In addition the device may be used to grade the seasoning of timber as well as the dielectric property of various materials. <IMAGE>

IPC: G06T15/40
Filed: 1987-02-20
Abstract: A display processor for processing polygon and vector data in a computer graphics system. In the polygon mode, data defining the edges of each polygon to be processed is provided to the display processor, and a series of "spans" are created by the processor, each of which defines the condition of each pixel within the polygon along a raster line of a display screen. Computations of color, intensity, and depth are made in parallel and the results stored in frame (22) and Z (23) buffers. In the vector mode, the condition of each pixel along the vector to be drawn is determined by the processor, with calculations of intensity and depth being carried out in parallel. Hidden surface and line removal is accomplished by the Z buffer (23).   <IMAGE>

Title: Increasing the spacing between receptacles of an endless conveyor
Inventor: HOLT JOHN BRIGGS
IPC: B65G23/30
Filed: 1989-03-08
Abstract: An endless conveyor assembly is operative to convey a group of items from a first location 27, at which the assembly presents stationary receptacles with a first receptacle-to-receptacle spacing, to a second location 44 at which the assembly presents moving receptacles having an increased second receptacle-to-receptacle spacing. The increased spacing may be achieved by means of chain links with slotted connections to allow relative movement in the longitudinal direction of the chain. The receptacles on the chain are preferably pivoted to discharge the article into a chute. At the loading station (27) the articles, which are preferably plants to be potted at station 44, are ejected from trays which are held vertically, the plants being horizontal. The trays are indexed downwardly by gravity being supported at each step by two reciprocable plungers. <IMAGE>

Title: Strain gauged turnbuckle
Inventor: BARRY STUART JOHN
IPC: F16B31/02
Filed: 1989-04-12
Abstract: A "turnbuckle" comprises an elongate support in the form of a frame, comprising generally parallel side arms 8, and end portions 10, 12 connecting the side arms in spaced, parallel relationship. Each of the end portions is provided with a threaded bore, the threads being of opposite hand, and extending through the threaded bores is a respective connector member (11, 13). The device comprises two strain gauges 16, 18, one secured to the inside of each of the two arms 8, the strain gauges having extending therefrom electrical connector means in the form of wires 20, conveniently connected to a socket 22.   In supporting a pipe, the turnbuckle is connected between a supporting structure and a cradle in which the pipe to be supported is located, and the device is "wound up", by rotation of the supporting frame relative to the connector members 11 and 13 until the load transmitted by the device, as determined by the output of a monitoring device, reaches an optimum value. <IMAGE>
Patent GB-2237816-A (GB)
Title: Isolator transfer containers
Inventor: COLES TIMOTHY PAUL
IPC: B01L1/02
Filed: 1989-11-09
Abstract: The transfer of materials into, and products out of, an isolator may be achieved, without compromising the containment, using a double-door transfer port (also known as a "rapid transfer port"). To make a contained transfer between the container and a lidded container, the container is "docked with" the closed port, and then from within the isolator the port door is opened. The docking of container to port may be accomplished using a bayonet system, and twisting the container around its axis to dock it into place at the port. Because the container must be physically rotated, the contents thereof are also subjected to rotation, which may spill liquids or damage delicate equipment. In order to overcome this problem, the whole of the lid (24) and bayonet-closure mechanism (35, 36) of the container (21) are housed in a short tube- or collar-like extension (30) of the container mounted on the container itself via a gas-tight slip-ring joint (30, 32). With such an arrangement, the extension is rotated to dock the container into place onto the port, but because of the slip-ring joint the container need not rotate. <IMAGE>

Title: Sampling water
Inventor: PASCOE EDWARD WILLIAM
IPC: F24F13/00
Filed: 1989-11-16
Abstract: In sampling water from mains or air conditioning systems to test for micro-organisms such as legionella, the water is passed through a filter comprising two sections 12, 14 to concentrate the micro-organisms, e.g. on a membrane 30. Section 14 is then unscrewed from section 12 and secured to a collecting chamber (32, Fig. 2) into which the collected micro-organisms are flushed by back-washing. In Fig. 1 membrane 30 is the finest of a series of filter members 22 to 30, but in Fig. 3 a loose bed of polystyrene latex particles with suitable antibodies thereon collects the micro-organisms desired and is thereafter flushed into the collecting chamber. The water can be sampled continuously in a by-pass passage or using a collecting funnel (Fig. 5) or a syringe may collect a series of samples and inject them consecutively through the filter (Fig. 8). <IMAGE>
Patent GB-2233764-A (GB)
Title: Determining sleep states
Inventor: KOYAMA EMI
IPC: G04G13/02
Filed: 1989-11-17
Abstract: A system for determining the sleep state of a person provides indexes representing the variation of a biological signal such as pulse or respiration rate on the basis of first variation amount denoting a trend with time of the biological signal from the start of measurement and second variation amount denoting the temporal variation of the biological signal, and discriminates different sleep states on the basis of the distribution density of the variation indexes exceeding a predetermined threshold, whereby NREM and REM sleep periods in particular can be reliably discriminated. This provides sleep information which enables an awakening stimulus to be generated shortly after termination of REM sleep to ensure a comfortable awakening. <IMAGE>
